I'm trying to use sequelize with typescript, but don't know how. I installed a package named sequelize-cli-typescript, but it does not work with sequelize v6. And I know it is better to use migrations to perform my database. How can I do that?

OK I just want to create my migrations with sequelize-cli, and output a ts file instead of js file. That's it, I don't wanna add models manually and then sync them. I just want to add models using migrations. sequelize-cli package is for js, not for ts. It generates js file,not ts.Hadi Ahmadi– Hadi Ahmadi2021-01-18 11:30:06 +00:00Commented Jan 18, 2021 at 11:30

You pretty much need to transpile your code into javascript if you're going to use migrations, because sequelize-cli doesn't know anything about typescript. We compile our stuff to ./dist right before running npx sequelize-cli db:migrate via npx tsc -p . with a tsconfig.json file that has these lines:
{
"compilerOptions": {
"target": "es6",
// ...
"outDir": "dist",
// ...
}
}
The .sequelizerc file (which is used by sequelize-cli only) will also point to dist, e.g.:
const path = require('path');
module.exports = {
'config': path.resolve('./dist/src/config', 'config.js'),
'models-path': path.resolve('./dist/src/db', 'models'),
'seeders-path': path.resolve('./dist/src/db', 'seeders'),
'migrations-path': path.resolve('./dist/src/db', 'migrations')
}

Use umzug. It powers sequelize cli.
